Of course, not every atheist is a killer. Many atheists are afraid of the reaction of their theistic neighbors or they retain some shreds of decency from theistic parents or grandparents. But, given free reign, how murderous could atheists become? Click here to find out.

Atheism is perhaps similar to anarchism. It may not explicitly advocate violence, however if widely accepted it does cause terrible destruction.

Nor is every theist, though you'll find a disproportionately higher number of theists have killed someone when compared to the number of atheists who have.

"Many atheists are afraid of the reaction of their theistic neighbors or they retain some shreds of decency from theistic parents or grandparents."

I don't even know most of my neighbors, theists or not, nor would I particularly give a damn what their reaction might be to anything that I might do.

Neither of my parents are religious in any way. When I was born I had only two surviving grandparents--one from each of my own parents--neither of whom were religious, or if they were never bothered to tell me about it.

"But, given free reign, how murderous could atheists become?"

Probably not very given that atheists recognize that society works better when we don't kill one another off left and right for petty reasons. Several theists quoted on this site, on the other hand, have outright stated that they would go on a murdering, raping, and pillaging spree were it not for their invisible friend keeping them in check. Which one seems scarier to you?

"Atheism is perhaps similar to anarchism."

Atheism has jack shit to do with anarchism, or any other "ism" you want to try to tack onto it.

"It may not explicitly advocate violence, however if widely accepted it does cause terrible destruction."

Here is someone deliberately misunderstanding atheism, communism and anarchism in order to slander them. Just like what we see on the internet in endless permutations every day.
This kind of propaganda is so crude and dishonest that sooner or later there will be a backlash against it.

Of course, not every Orthodox Jew sexualizes prepubescent children. Many fear to spit on, throw stones at, or scream abuse at children whom they find provocatively dressed because of their non-Orthodox neighbors. But, given free reign, how depraved could Orthodox Jews become? Click here to find out.

Even if atheism were the same as nihilism, this would still be an appeal to consequence - a well known logical fallacy. If you don't like the implications of a premise, DEAL WITH IT, because it doesn't make the premise any less true.

With apologies to G.K. Chesterton (especially since the book was a Christian allegory):

"Mere unbelievers! So you talk about atheists and pagans as if they were the question. You've got that eternal idiotic idea that if anarchy came it would come from the Godless. Why should it? The unbelievers have been rebels, but they have never been anarchists; they have more interest than anyone else in there being some decent government. The people of diverse opinions really have a stake in the country. The man pushing single faith hasn't; he can go away to convert other countries by sword. The tolerant have sometimes objected to being governed badly; the narrow-minded have always objected to being governed at all. Theocrats were always anarchists, as you can see from the Crusades."

Of course, not every devout Jew is a foaming rabid jackass with a mouth full of weasel words ... But "perhaps" this guy is. Qualified hate speech is still hate speech. You have become your own worst nightmare.

The vast numbers of mass murders have been done by "believers" in the name of "Gahd". The Fifteenth Century alone so scores of thousands killed by Vlad the Impaler, over a million by the Inquisition, and by the end of that century, the beginning of the same in the Americas. That's just Western Christianity, folks (the Impaler converted thereto from Eastern Orthodoxy). The Eastern Church, Islam, and Old Testament Judaism all had similar blood on their hands, and G.W. Bush's frightening "Gog and Magog" letter makes it clear that religious bigotry played as important a part in his decision to murder a nation as greed. Hitler was not an atheist. He simply believed he, himself, was "Gahd", and was even establishing a church where he'd be worshipped. Atheists who believe all life and being are extinguished at physical death are in many cases a lot more discreet about dealing it out, and at least those who do don't go on to gloat over their victims burning forever and ever in Hell.

There are many examples of atheist and theist persons being murderers. You can't say that if atheism is widely accepted it will cause terible detruction. As atheism has never been widely accepted, you have no evidence to support that slur.

P.S. I resent your implying that decency in atheists stem from their theistic parents. That too is an unsupportable claim.

Is that kind of like how Jews drink baby blood, poison wells, and profane the Eucharist? You folks do do that right? It's not just a bunch of bullshit pulled out of someone's ass to dehumanize you, or anything, right?
